I have a CDK app which I generate template.yml file using:
cdk synth --no-staging > ./template.yml
and then run sam local:
sam local start-api
but I get the following error:

ValueError: not enough values to unpack (expected 2, got 1)
and ideas what's the issue?
It might be that you have an older version of AWS SAM. I have multiple projects that implement AWS CDK and use AWS SAM for local testing and they work without any issues!
Your AWS SAM version seems to be 1.37.0, try to upgrade to the latest version and see if that allows you to use the two together.
As a reference point: one of my projects uses AWS CDK version 2.53.0 with AWS SAM version 1.78.0.
